FIELD OF THE DISCLOSURE

The disclosure relates to the field of lipstick technologies, and moreparticularly to a sealed lipstick tube.

BACKGROUND

Lipsticks have the advantages of high color saturation and strong hidingpower, thereby becoming the most commonly used cosmetics for modernwomen. It is commonly used by users to modify the lip shape and lipcolor. The lipstick is generally tubular shaped, and a lipstick tubegenerally includes a cartridge sleeve for accommodating the lipstick,and a cover body covering the cartridge sleeve. The cartridge sleeve andthe cover body are snapped and connected together. However, theabove-designed lipstick tube has poor sealing effect, especially usedfor a long period of time. The above-designed lipstick tube has a poorsealing effect, especially after long time usage. Because there is a gapin the snap connection between the cartridge sleeve and the cover body,it is easy to cause the outside air to enter the inside of the tube, sothat the lipstick is contaminated and the volatilization is accelerated.

Please referring to FIGS. 1 to 3, FIG. 1 is an exploded structure viewof a sealed lipstick tube in the embodiment, FIG. 2 is an enlarged viewof part A of FIG. 1, and FIG. 3 is a cross-sectional view of the sealedlipstick tube.

This embodiment provides a sealed lipstick tube, including a housingbase 1, a housing inner tube 2, a cartridge 3 for disposing a lipstick,a sealing sleeve 4, and a housing outer tube 5. The housing base 1, thehousing inner tube 2, the cartridge 3, and the housing outer tube 5 eachare tubular-shaped structures. An outer wall of the housing base 1 isprovided with an annular engaging groove 11 around an axis of thehousing base 1, and an inner wall of the housing inner tube 2 isprovided with an annular engaging protrusion 21 around the axis of thehousing base 1. The housing base 1 and the housing inner tube 2 areengaged together, by enabling the annular engaging protrusion 21 to befitted and clamped in the annular engaging groove 11. The housing base 1and the housing inner tube 2 are made of hard plastic material, and whenthe annular engaging protrusion 21 is fitted in the annular engaginggroove 11, a buzzing sound is generated to remind the user to snap inplace. The housing base 1 and the housing inner tube 2 cooperativelydefine an installation space 6, and the installation space 6 is largerthan a volume of the cartridge 3. The cartridge 3 is mounted on thehousing base 1 and is located in the installation space 6. The sealingsleeve 4 is fixed at the end of the housing inner tube 2 that adjacentto the annular engaging protrusion 21, and an inner wall of the sealingsleeve 4 abuts against the outer wall of the housing base 1. The sealingsleeve 4 can be fixed on, the housing inner tube 2 by means of injectionmolding to strengthen the firmness thereof. The housing outer tube 5 issleeved on the outer wall of housing inner tube 2 and an outer wall ofthe sealing, sleeve 4 at the same time that is, the housing outer tube 5simultaneously encapsulates the housing inner tube 2 and the sealingsleeve 4, thereby protecting the housing inner tube 2 and the sealingsleeve 4. In addition, the housing inner tube 2 and the sealing sleeve 4can be designed as the same color, so that the appearance of the productis more neat and beautiful. In the present application, the sealingsleeve 4 is made of a TPE (Thermoplastic Elastomer) material with highstrength and high elasticity, or a silicone material, or a mixedmaterial of TPE and silicone. These materials can effectively improvethe sealing performance of the sealing sleeve 4. Of course, the sealingsleeve 4 can also use other materials as long as it can have a propersealing effect.

Further, referring to FIG. 2, the inner wall of the sealing sleeve 4 isprovided with an annular sealing protrusion 41, and a cross-sectional ofthe annular sealing protrusion 41 is tapered. The annular sealingprotrusion 41 utilizes a protruding portion, to abut against the outerwall of the housing base 1, thereby further improving the sealing effectof the sealed lipstick tube of the disclosure.

Further, referring to FIG. 4 and FIG. 5, FIG. 4 is an exploded structureview of another perspective of the sealed lipstick tube in theembodiment, and FIG. 5 is an enlarged view of part B of FIG. 4. Anannular fixing groove 42 is defined in the sealing sleeve 4. The annularfixing groove 42 matches the nozzle of the housing, inner tube 2 inshape and size. The annular fixing groove 42 engages with one end of thehousing inner tube 2, that is, it is stuck at the nozzle of the housinginner tube 2. A plurality of fixing holes 22 are defined in the tubewall of the housing inner tube 2, uniformly distributed around the axisof the housing base 1. A plurality of fixing posts 43 corresponding tothe plurality of fixing holes 22 are disposed in the annular fixinggroove 42, and each fixing post 43 passes through a corresponding fixinghole 22. The annular fixing groove 42, the fixing holes 22, and thefixing posts 43 constitute a fixing mechanism, which can furtherstrengthen the fixing of the sealing sleeve 4 on the housing inner tube2 and prevent, the sealing sleeve 4 from falling off. So, the sealingand the waterproof performance of the sealed lipstick tube of thedisclosure are ensured to be stable and effective.

Further, referring to FIG. 3, the cartridge 3 includes a cartridge base31, a cartridge sleeve 32 a screwing tray 33, and a screwing rod 34. Thecartridge base 31 is mounted on the housing base 1 by means of glue. Anouter wall of the cartridge base 31 is provided with a plurality offixing protrusions 311, and these fixing protrusions 311 can prevent thecartridge base 31 from rotating in the housing base 1. An end of thecartridge sleeve 32 is movably connected with an end of the cartridgebase 31. In detail, a rotation fixing groove 321 is defined in thecartridge sleeve 32, the end of the cartridge base 31 is fittinglyengaged in the rotation fixing groove 321 and forms a clearance fit withthe cartridge sleeve 32, so that the cartridge sleeve 32 can be rotatedabout its axis relative to the cartridge base 31. The screwing tray 33is disposed in the cartridge sleeve 32. The screwing rod 34 is threadedwith and penetrates through a central portion of the cartridge base 31.The screwing rod 34 and the cartridge base 31 are engaged together bythreads. One end of the screwing rod 34 is connected to the screwingtray 33. When in use, the user holds the cartridge sleeve 32, and thenrotates the cartridge base 31 to control the extension and retraction ofthe screwing tray 33. A columnar lipstick may be positioned at thescrewing tray 33 and received in the cartridge sleeve 32, as therotation of the cartridge base 31, the lipstick can be correspondinglyextended out from or retracted into the cartridge sleeve 32. Thescrewing tray 33 includes a number of rod-shaped fixing elements 331fixed therein, the fixing elements 331 are configured for inserting,into the lipstick and thereby increasing the bond between the lipstickand the screwing tray 33. The fixing elements 331 are adjacent to thecartridge base 31, and are uniformly distributed around the axis of thecartridge base 31. The cartridge base 31 is coaxial with the housingbase 1. Actually, the housing base 1, the housing inner tube 2, thecartridge 3, the sealing sleeve 4, and the housing outer tube 5 arecoaxial. When the lipstick is not in use, the lipstick can be hidden inthe cartridge sleeve 32. In this way, the effect of preventing thelipstick from being contaminated when not in use is achieved.

In summary, the design of the sealed lipstick tube of the presentdisclosure is simple. The engagement between the housing base 1 and thesealing sleeve 4 fixed on one end of the housing inner tube 2 is usedfor sealing, so that the sealing performance of the sealed lipstick tubeof the present disclosure is good. In addition, the housing outer tube 5is sleeved at the outer walls of the housing inner tube 2 and thesealing sleeve 4, the housing outer tube 5 is capable of protecting thehousing inner tube 2 and the sealing sleeve 4, thereby increasing theservice life of the sealing sleeve 4. Final, the housing, base 1, thehousing inner tube 2, and the housing outer tube 5 form an integralstructure, so that the appearance of the product is neat and beautiful.
